SoFi Bank has expanded the availability of its SoFiUSD (SOFID) stablecoin to the Polygon blockchain, giving customers another network through which they can access and manage the dollar-pegged digital asset. The deployment, announced by Polygon Labs on Thursday, marks the stablecoin’s expansion to a third blockchain following its earlier availability on Ethereum and Solana.
The integration allows SoFi members to purchase, sell, hold, and convert SoFiUSD directly through the bank’s mobile application. Customers can access the token without establishing an external cryptocurrency wallet or manually transferring their holdings between blockchain networks.
The Polygon deployment expands SoFiUSD’s multi-chain availability while allowing customers to manage their stablecoin holdings through a familiar banking application without additional wallet infrastructure.
The development highlights SoFi’s efforts to broaden the utility of its digital dollar token and connect traditional banking services with blockchain-based payment networks.
SoFiUSD Expands Beyond Ethereum and Solana
SoFi initially introduced SoFiUSD in December 2025, with the stablecoin designed to support settlement activities involving banks, financial technology companies, and enterprise partners.
The company subsequently expanded access to individual members through its mobile application in May 2026, initially supporting Ethereum and Solana. The addition of Polygon provides another blockchain option for customers and institutions using the digital dollar.
With the latest deployment, SoFiUSD operates across three blockchain networks, potentially increasing its accessibility within different digital asset ecosystems.
The in-app integration also simplifies the customer experience by removing the need to manage separate wallets or independently handle cross-chain transfers. Members can perform supported transactions within SoFi’s existing application environment.
This approach could make stablecoin services more accessible to customers who want to use blockchain-based digital dollars without directly interacting with the technical processes involved in managing cryptocurrency wallets and network transfers.
Polygon’s Open Money Stack Supports Financial Connectivity
On Polygon, SoFiUSD becomes part of the network’s Open Money Stack, a payments infrastructure initiative designed to connect banks and financial technology companies with stablecoins and local currencies.
The infrastructure aims to provide financial institutions with tools to connect existing customer accounts to blockchain-based payment systems. This could help businesses integrate digital currency settlement into their financial operations without requiring customers to independently navigate blockchain networks.
For SoFi, the Polygon integration extends the existing functionality of SoFiUSD while potentially opening access to additional payment and financial applications within the Polygon ecosystem.
The deployment also reflects the growing interest among traditional financial institutions in using blockchain networks to support digital dollar transactions.
Polygon’s infrastructure provides another environment for stablecoin activity, while SoFi contributes an established banking and financial services platform with an existing customer base.
Stablecoin Redeemable One-for-One Against the U.S. Dollar
SoFiUSD is designed to maintain a one-to-one redemption relationship with the U.S. dollar, allowing eligible holders to redeem the digital token for an equivalent amount of U.S. currency.
However, the stablecoin carries important distinctions from conventional bank deposits and investment products. SoFi has clarified that SoFiUSD is not a bank deposit and does not receive insurance protection from the Federal Deposit Insurance Corporation (FDIC) or the Securities Investor Protection Corporation (SIPC).

These distinctions are important for customers evaluating the risks associated with holding digital assets. Although the token is designed to maintain dollar parity, it should not be treated as equivalent to an insured bank account.
The availability of redemption in U.S. dollars provides a mechanism for converting the digital asset back into conventional currency, while the absence of deposit insurance means customers must understand the protections and risks associated with the product.
Multi-Chain Stablecoins Gain Banking Industry Attention
The expansion of SoFiUSD reflects a broader trend toward integrating stablecoins into conventional financial services. Financial institutions are increasingly exploring blockchain networks for payments, settlement, and digital currency distribution.
By supporting Ethereum, Solana, and Polygon, SoFi is extending its stablecoin infrastructure across multiple blockchain ecosystems rather than restricting its digital dollar to a single network.
The Polygon integration strengthens SoFiUSD’s role as a multi-chain payment asset, combining dollar-denominated digital transactions with direct access through the bank’s existing mobile application.
The expansion could provide SoFi members with greater flexibility in accessing blockchain-based financial services while supporting the company’s longer-term efforts to connect traditional banking operations with digital asset infrastructure.
